If '+' means 'division', '÷' means 'multiplication', '–' means ‘addition' and ‘×' means ‘subtraction', then find the value of

15 + 3 – 8 ÷ 9 × 7

Given: 15 + 3 – 8 ÷ 9 × 7

Given equation is solve by BODMAS rule.

​$$\begin{array}{|c|c|} \hline\textbf{Operation preference wise} & \textbf{Symbol} \\\hline\text{Brackets} &[],{}, () \\ \hline \text{Orders, of} & (power), √ (root) , of \\ \hline \text{Division}& ÷ \\ \hline \text{Multiplication} & × \\ \hline \text{Addition} & + \\ \hline \text{Subtraction} & - \\\hline\end{array}$$

New equation 15 $$\div$$​ 3 + 8 $$\times$$​ 9 - 7

= 5 + 8$$\times$$​9 - 7

= 5 + 72 - 7

= 77 - 7

= 70

Thus, correct option is (d).
